Multiple Random Image With Corresponding 'alt' Tags?
Nov 19, 2009
I implemented some coding tor create a random image on the page with a corresponding 'alt' tag and all was fine for a while...Then I got ambitions and modified the script to generate code that would generate two seperate sets of random image and associated 'alt' tag pairs.... and all seemed fine for a while....... however after having used the code on my page for a while I notice that occasionally I get a broken file link to the image which then fails to show... and shows the 'alt' text of "undefined".All the code links to images are correct and all images DO show from time to time with the tags.... only occasionally this extra blank/undefined pair is generatedHere's the code...
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
// Set up the image files to be used.
What I have is a site with about 10 pictures, each of these pictures needs to be randomly pulled from folders, each picture slot will have its own folder, due to it being categorized. When the picture is clicked i need it to open a new page with the document associated to the picture. Is there a way to do this without having to rewrite the code every time? Because as there are new documents added at the end of each week.Unfortunately the server I use doesn't support PHP, but if it has to be done in PHP I can switch.Like I said though I haven't messed around with web design in a long time
What I'm looking to do is have a folder of images that I have show up on my website.I'm also looking to pull from this folder up to 6 or 7 times on the same page w/ randomized pictures that do not repeat.Finally, I'm looking to be able to size and name these images based on which image randomly pulls. b/c it's not grabbing the images.
I'm trying to use Javascript to have an array of images that load randomly AND work in a slideshow manner so change every 3 seconds (in a logical order). The code I have below presents a random image but how do I get them to continue from the random image and change to the next every 3 seconds?
I've been searching for a resolution to this issue for hours trying to customize my page located at [url]
Specifically, I'm trying to figure out why this line of code is not making my images display in the background:
Original plugin script provided here: [url]
<script>
I made adjustments with my image references that are all located in this directory: [url]
Problem: No images load, and I believe I don't fully understand the .appendTo tage.. I don't know if #body is correct. The author of the plugin assumed I understood the relation. Also #homePage may be incorrect as well.
Additionally, I found another plugin that worked for placing an image in the background (not random), and the background image would scale to size, according the users window. I loved that and it worked, just wanted to add random images to the same script.... first things first... I can't even get an image to display at all with the above code.
In case you wanted to know the script I was using to scale the background image, here it is below (although, as you will see in the code for my site - this image feature is disabled as I am trying to make adjustments).
code for image solutions used:
HTML
CSS
If I can get this second code to work with the random image plugin.
Here's what I usually use and have been using for years and it works great, just not for this particular purpose. I don't have a clue when it comes to javascript.
<noscript><img src="no_script_quote.gif" width="406" height="94"/></noscript><script language="javascript"> var delay=6000 var curindex=0
[code]....
But, now I want to be able to set a default picture to be shown first and have the random pics appear next. I also don't want the default pic to show up again in the random array. So basically, every time the page was first visited, or refreshed it would show the default picture then move into the random pics.
I have a webpage that contains a ton of php code. Every so often I need a jquery to update a few areas of the page. I can make a separate jquery for each div tag but it would be a lot simpler if I could update each using the same jquery. This is my code for updating div tag predators..... <!-- Only updates single div tag. look into updating multiple div tags in same jquery--> <script src="[URL]"></script> <script> $(document).ready(function() { $("#predators").load("predators.php"); var refreshId = setInterval(function() { $("#predators").load('predators.php?randval='+ Math.random()); }, 9000); $.ajaxSetup({ cache: false }); }); </script> The big question is; is it possible?
I have a script which allows me to select random users from one select field to another and works like a charm, but...I want to be able to get random users from one select field to multiple (lets say 2) other select fields...So lets say that I have 5 users in the first field (select1):
James Bill Jennifer Bob Karen
Now when I press a button: <input value="" type="button" onClick="randomusers();" />
2 users should be moved to select2 and other 2 users moved to select3.My current script is as follows:
function randomusers(){ var given = 2, used = {}, randnum, opts = $('#select1 option'), olen = opts.length, hiddiv = $('#hiddendiv'); function ran() { // generate a unique random number[code].....
I have a quick question with multiple array and random numbers. If i generate my random numbers in one array, how would i take a selection of those numbers and put them in another array?
Ex: array 1: 25, 34, 38, 40, 22, 49
Want to move numbers between 30 and 50 to another array.
array 2: 34, 38, 40, 49
Is it as simple as for loops and if statements setting the conditions? do i use a sorting method? (selection? bubble?)
I'm completely new to this and have no knowledge at all when it comes to javascript. Have been using this script on my site for a while. Is there anyway I can add a URL link to the images that are in my selector? When clicked would go to that page on my website.

I have several pages, all with multiple select boxes. Each select has a different name, but contains the same values (ok, not ok, fixed, needs fixing). I am trying to write a single script that will loop through each select box on the page, find all the 'not ok' values, then send the select box name, with the option value to a holding area (probably an array) which will be emailed to someone once all the pages have been entered by the user.
At this time, I am just trying to figure out the looping through one page of select boxes. The script is currently tied to an onclick event for the submit button.
I've been asked to do the following using javascript:
-Create a function named randInt() with one parameter of "size". Declare a variable named "rNum" equal to a random integer between 1 and the value of the size variable. Return the value of the "rNum" varialbe from the function.
-Create a function named getQuote() with one parameter anemd "qNum". The function should create an array named mtQuotes with five quotes; there should be no quote for the array index "0". Return the value of the mtQuotes array for the qNum index.
- In the div element of "quotes" insert a script with the following commands: Declare a variable named "randValue" which is euqal to a random integer between 1 and 5 (use the randInt() function). Declare a variable named "quoteText" containing the quote whose array index value is equal to randValue. Write the value of quoteText to the web page.Here is what I have...it returns undefined.

The application I'm working on dynamically generates a HTML table like the one below. Having identified that I need to add an opening <tbody> before the first TR that contains the word "Diagnosis", opening + closing TBODY to all other TRs containing the word "Diagnosis" & Closing </TBODY> after the last closing TR?
I would like to hide/show the relevant divs (into a container) based upon the button pressed. If no div was open, then it would simply open the relevant div, however if say div 2 was open and div 3 was pressed, div 2 would toggle closed then div 3 would toggle open.
I've got each individual div opening and closing, but I'm stuck at the next point (checking if a div is open/toggling etc).
I am using a module called mod_pageear in my joomla based site that displays an image in the page when the trigger is scrolled over. I would like to change the code to access images in a folder on a random basis. The existing section of the code that accesses the single image is as follows: Code:
I am using jquery with the cookie plugin and I have multiple image buttons that can hide/show multiple elements. My question is how can I add a cookie to this code to remember whether each separate element is opened or closed?
The code, $(document).ready(function() { // choose text for the show/hide link - can contain HTML (e.g. an image) var showText='<div class="expanddown"></div>'; var hideText='<div class="expandup"></div>'; // initialise the visibility check var is_visible = false; // append show/hide links to the element directly preceding the element with a class of "toggle" $('.toggle').prev().append('<a href="#" class="togglelink">'+hideText+'</a>'); // capture clicks on the toggle links $('a.togglelink').click(function() { // switch visibility is_visible = !is_visible; // change the link depending on whether the element is shown or hidden $(this).html( (!is_visible) ? hideText : showText); // toggle the display - uncomment the next line for a basic "accordion" style //$('.toggle').hide();$('a.toggleLink').html(showText); $(this).parent().next('.toggle').slideToggle('fast'); // return false so any link destination is not followed return false; }); }); HTML, <a class="togglelink" href="#"></a> <div class="toggle"> Content </div>
I have a page on which a random image loads. Each image needs an accompanying image map to take you to the appropriate link. How do I make the appropriate image map links load? Here is my code so far, which works fine.
myStrip = new Array("images/hstrip_1.jpg","images/hstrip_2.jpg"); imgCt = myStrip.length;
function chooseStrip() { if (document.images) { randomNum = Math.floor((Math.random() * imgCt)); document.strip.src = myStrip[randomNum]; } }
I'm hoping that someone can answer what is probably a really simple question. I've got the Random Image Slideshow script from javascript.com and have it placed in my site where I want it. Now how do I get it to read where I've got the images I want displaying? The folder I have is called homeimages with 10 photos currently inside it.
im having a dumbass problem its probably something stupid as it always is with me. Basically ive incorporated a javascript random image background. It works however it occasionally displays a WHITE bg, as if its trying to link to one of the images in the array and its not there. To get what i mean view the link below and click REFRESH until it goes white. Code:
